A display device includes a laminated wiring formed of a low-resistance conductive film, and a low-reflection film mainly containing Al and functioning as an antireflective film which are sequentially arranged on a transparent substrate, a wiring terminal part provided at an end part of the laminated wiring and has the same laminated structure as that of the laminated wiring, and an insulating film for covering the laminated wiring and the wiring terminal part, in which the insulating film side serves as a display surface side, the wiring terminal part has a first opening part penetrating the insulating film and the low-reflection film and reaching the low-resistance conductive film, and an outer peripheral portion of the first opening part has a laminated structure of the low-resistance conductive film, the low-reflection film, and the insulating film, in at least one part.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A display device comprising: a laminated wiring comprising a conductive film, and an antireflective film sequentially arranged on a base layer; a wiring terminal part provided at an end part of said laminated wiring and having a same laminated structure as that of said laminated wiring; and an insulating film for covering said laminated wiring and said wiring terminal part, in which said insulating film side serves as a display surface side, wherein said wiring terminal part has a first opening part penetrating said insulating film and said antireflective film and reaching said conductive film, and an outer peripheral portion of said first opening part has a laminated structure of said conductive film, said antireflective film, and said insulating film, in at least one part.
2. The display device according to claim 1 , further comprising: at least one of a mark and an identification mark covered with said insulating film and used in a manufacturing step, wherein each of said mark and said identification mark comprises: a laminated film of said conductive film and said antireflective film, and a second opening part penetrating said insulating film and said antireflective film and reaching said conductive film, and an outer peripheral portion of said second opening part has a laminated structure of said conductive film, said antireflective film, and said insulating film, in at least one part.
3. The display device according to claim 1 , further comprising: a mark covered with said insulating film and used in a manufacturing step, wherein said mark comprises: a laminated film of said conductive film and said antireflective film, and a film thickness of said antireflective film of said laminated film is formed to be thinner than a film thickness of said antireflective film of said laminated wiring.
4. The display device according to claim 3 , wherein a film thickness of said antireflective film of said wiring terminal part is formed to be the same as a film thickness of said antireflective film of said mark.
5. The display device according to claim 1 , further comprising: a mark covered with said insulating film and used in a manufacturing step, wherein said mark comprises: a laminated film of said conductive film, said antireflective film, a cap film functioning as an etching protective film, and a non-low-reflection film having reflectivity of 30% or more.
6. A display device comprising: a laminated wiring comprising a conductive film, and an antireflective film sequentially arranged on a base layer; a wiring terminal part provided at an end part of said laminated wiring; and an insulating film for covering said laminated wiring and said wiring terminal part, in which said insulating film side serves as a display surface side, wherein said wiring terminal part comprises said conductive film, said wiring terminal part has a first opening part penetrating said insulating film and reaching said conductive film, and an outer peripheral portion of said first opening part has a laminated structure of said conductive film, and said insulating film, in at least one part.
7. The display device according to claim 6 , further comprising: a mark covered with said insulating film and used in a manufacturing step, wherein said mark comprises said conductive film.
8. A display device comprising: a laminated wiring comprising a conductive film, and a multilayered reflection reducing film having a reflection preventing effect due to a light interference effect, sequentially arranged on a base layer; a wiring terminal part provided at an end part of said laminated wiring and having a same laminated structure as that of said laminated wiring; and an insulating film for covering said laminated wiring and said wiring terminal part, in which said insulating film side serves as a display surface side, wherein said wiring terminal part has a first opening part penetrating said insulating film and said reflection reducing film and reaching said conductive film, and an outer peripheral portion of said first opening part has a laminated structure of said conductive film, said reflection reducing film, and said insulating film, in at least one part.
9. The display device according to claim 8 , further comprising: a mark covered with said insulating film and used in a manufacturing step, wherein said mark comprises a laminated film of said conductive film, and said reflection reducing film having at least one layer removed or thinned.
10. The display device according to claim 8 , wherein said reflection reducing film comprises a transparent film and a translucent film sequentially arranged on said conductive film.
11. The display device according to claim 8 , wherein said reflection reducing film comprises a transparent film, a translucent film, and a transparent film sequentially arranged on said conductive film.
